I am currently trying to port an embbeded Linux from a older i.MX6s to a newer industial model:
(MCIMX6S5EVM10AB to MCIMX6S7CVM08AC)
Linux arm 3.0.35+ #1 PREEMPT armv7l GNU/Linux
While I do not see any notable difference in the booting process as well as during runtime itself, it sometimes happens (1 out of 5) that the boot process freezes completly during the initalization of the imx-ipuv3 and the only solution is powering it off and on again.
It freezes before the info line:
imx-ipuv3 imx-ipuv3.0: IPU DMFC NORMAL mode: 1(0~1), 5B(4,5), 5F(6,7)
can be printed out.
This behavior can be reproduced independent of the U-Boot or the Hardware used.
Is there an important difference in those two CPU which I completly overlooked ?
Thanks in advance for the help
